That was not what I asked. Please test without ipappend
and use ip=dhcp as a kernel parameter instead. Don?t forget
to enable dhcp autoconfiguration in the kernel config ...

I bet that you will see that the same dhcp server that proved to
work correctly by providing your server ip etc to the
pxe bootrom and via ipappend to the kernel is unable to
give that same information to the linux ipconfig code
directly. Please try and report.

I assume that you do not have any problem to pxeboot good
old DOS and memtest. Right?

Please give board name, bios version, pxe rom version, and
lspci -vv.

If I am right with my bet the problem is unrelated to the tcp / udp
choice and unrelated to ipconfig, portmap lookup and nfsroot code.
